In this post, i will share on how to update and install the RPM packages from CD-ROM/DVD-ROM image on CentOS 6.2. This will very useful when you are running on slow internet connection. Instead of go through the internet connection, it is possible to use Local CD/DVD-ROM as your yum repository. There are two methods to install and configure local CentOS 6.2 yum repository. Both methods have been tested and working on CentOS 6.2 linux server. You can select any method that you most preferred. This may be also applicable on other version of CentOS server.
Method 1:
1. Insert DVD/ISO into DVD-Drive.
2. Mount the ISO from the DVD-ROM into /mnt directory :
[root@centos62 ~]# mount /dev/cdrom /mnt
mount: block device /dev/sr0 is write-protected, mounting read-only3. Create centos62.repo text file in /etc/yum.repos.d/ with the following content. Please create something as follow:
[root@centos62 ~]# vi /etc/yum.repos.d/centos62.repo[CentOS6.2-Repository]
name=DVD-CentOS6.2 repository
baseurl=file:///mnt
enabled=1
gpgcheck=04. Finish. You can start install, remove and update using yum command :
Example :
[root@centos62 ~]# yum install httpd -yMethod 2 :
1. Check the existing partition on your CentOS 6.2 server
[root@centos6 ~]# df

/dev/sda1 495844 29842 440402 7% /boot2. Create localrepo directory in /mnt :
[root@centos6 ~]# mkdir /mnt/localrepo3. Create 1 2 3 directory in /mnt/localrepo
[root@centos6 ~]# mkdir -p /mnt/localrepo/{1,2,3}4. Mount the ISO from the DVDROM into /mnt/localrepo/1 directory
[root@centos6 ~]# mount -o loop /dev/cdrom /mnt/localrepo/1[root@centos6 ~]# df -lh

[root@centos6 ~]# mkdir /tmp/repo6. Copy the require pacckages to install create repo:
[root@centos6 ~]# cp /mnt/localrepo/1/Packages/createrepo* /tmp/repo
[root@centos6 ~]# cp /mnt/localrepo/1/Packages/deltarpm* /tmp/repo
[root@centos6 ~]# cp /mnt/localrepo/1/Packages/libxml2-python* /tmp/repo
[root@centos6 ~]# cp /mnt/localrepo/1/Packages/python-deltarpm* /tmp/repo
[root@centos6 ~]# ls /tmp/repo

[root@centos6 ~]# rpm -ivh /tmp/repo/*

[root@centos6 ~]# cd /mnt/localrepo/9. Run createrepo command :
[root@centos6 localrepo]# createrepo .
